Abstract
An emergency shut-off valve includes a valve assembly positioned within a valve body and an actuator assembly operatively coupled to the valve assembly. A poppet is coupled to a shaft having a retaining member positioned within a slot in an arm of the poppet to prevent the poppet from being removed from the shaft. A gland has a first slot, a second slot opposite the first slot, where the first and second slots are configured to receive an end of a torsion spring, and a flange. An O-ring is positioned within a recess in the valve body at the outer surface to engage the flange to provide a seal between the gland and the valve body.
